摘要: A fast high-power solid-state switch based on a novel large periphery multigate AlGaN/GaN metal-oxide-semiconductor heterostructure field effect transistor (MOSHFET) over 4H-SiC substrates is demonstrated. For device with 1 mm and 10 µm gate-drain spacing, 7.5 kW/mm2 of switched power on-state resistance 75 mΩ × mm2 obtained. The pulse response the MOSHFET exhibited rise-time < 5 ns in pulsemode operation.
